The dual-bell nozzle is a promising altitude adaptive nozzle concept for improving the performance of existing space launchers as well as future reusable launch vehicles. It is characterized by an inflection in the wall geometry which links a base no
The established state-of-the-art for composite solid propellant grain manufacture consists in mix-cast-cure process using hazardous chemicals and specific molds for propellant forming. In most of the cases, polyaddition of oligomers involves isocyana

The application of dual-bell nozzles to existing space launchers offers the possibility to significantly increase their payload capability. This benefit is related to the ability of this kind of nozzles to switch between a low-altitude and a high-alt

A low-order model for a hybrid rocket engine is proposed to investigate low-frequency combustion instabilities. The present work is based on a one-way coupling between a one-dimensional thermal model to evaluate the unsteady regression rate and a zer

The work reported herein is a preliminary numerical study of a resonant igniter for rocket engines. Resonant igniters are very attractive and promising for in-space thrusters, since they are simple, highly reliable and lightweight. Fine-tuning of var

A novel internal ballistics technique for determining the time-resolved spatially averaged regression rate of the solid-fuel grain in a hybrid rocket engine is presented. This technique makes use o...
